According to the EPA, regular cleaning with a central vacuum system that is vented to the outside can reduce allergy-causing agents and rid your home of biological contaminants such as dust, bacteria and pollens. Low Voltage Service’s built-in central vacuum system offers the added advantage of Vacuflo® patented True Cyclonic Separation which eliminates the need for messy bags or vacuum filters that can clog and reduce cleaning effectiveness over time. 96 - 98% of the dust and dirt sucked into the system is deposited into the clear dirt canister, while the remaining 2 - 4% is exhausted to the outdoors.
